  2. Interior Quality – Candling On Egg Farms In 4-H Judging Contest Hold only ONE egg at the time

  3. Candling • Hold small end of egg with thumb, index, and middle fingers • Put large end of egg against candler at a 45 degree angle • Carefully rotate egg • Look for blood / meat spots • Check size of air cell, yolk shadow

  4. Interior Egg Quality • Graded as AA, A, B, and inedible • Size of Air Cell is generally most important when there is no blood/meat spot • Yolk Shadow Outline – determined by albumen thickness • Size and Shape of Yolk

  5. Interior Quality – Air Cell • Smaller = Higher Quality

  6. AA - Air Cell is 1/8 inch deep (bottom left) A - Air Cell is 3/16 inch deep (bottom center) B - Air Cell is 3/8 inch deep (bottom right)

  7. Interior Quality – Yolk Shadow • If the albumen is thick, the shadow of the yolk will be harder to see. AA Quality = Outline slightly defined A Quality = Outline fairly well defined B Quality = Outline plainly visible

  8. AA Quality • Air Cell = 1/8 inch • Yolk Shadow = Slightly defined

  9. A Quality • Air Cell = 3/16 inch • Yolk Shadow = Fairly-well defined

  10. B Quality • Air Cell = 3/8 inch • Yolk Shadow = Plainly Visible
